APPARATUS FOR MOUNTING STEREOGRAPHS- 4- Specification of Letters Patent. Patented Nov. 21, 1905. Application filed March '25, 1903. Serial No. 149,564.

To all whom it may concern:

Beitknown that I, CHARLES S. BEAoH,of the village of Bennington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Apparatus for Mounting Stereographs, of which the subjoined description, in connection with the accompanying two sheets of drawings, constitute a specification. 7

IO The invention relates to means for mounting gummed sterescopic prints (commonly called stereographs) while wet upon stiff card-mounts, applying to the mounted prints ferrotype-plates while still wet, subjecting 5 the assemblage in this condition to initiatory pressure to fasten the several parts together, and delivering the assemblage, which is called a pack, to a receptacle called a pressbox, which is automatically and intermittently moved along step by step by special mechanism to receive the packs as they are delivered to it. The operations of the pressboX carriage are initiated by the automatic action of the pack upon an escapement-lever 5 as it leaves the press-rolls, as will more clearly appear further on.

The mounting-frame 60 (shown in Fig. 2) constitutes an element in some of the combinations herein claimed and is the subject-mat- 3 ter of Letters Patent N o. '7 59,949, dated May 17, 1904, to which reference may be made for specific description thereof.

The drawings fully disclose the invention, wherein Figure 1 shows a side elevation of the front of the right hand end of the machine with some parts broken away to expose otherwise concealed parts. No part of the frame is shown where it is unessential to a clear understand- 4 ing of the apparatus. Fig. 2 is a top plan view of the parts seen in Fig. 1. Fig. 3 is an elevation of the rear of the press-box frame and carriage and its actuating apparatus as seen in Fig. 1. Figs. 4, 5,and 6 are respectively front, edge, and front elevations of the scape-wheel and pallets which control the movements of the press-box carriage. Fig.

7 is a side view, and Fig. 8a rear View, of the l section through one of the crank-wrists of the scape-wheel shaft. Fig. 10 shows aside elevation of those parts of the machine not shown in Fig. 1.

The apparatus is arranged on a long table 1, on opposite sides of which several operatives can sit. Abreast of each operative a mounting-frame 60, Fig. 2, is provided, in which the pasted prints are adjusted and stuck to the cards, as described in said patent. This frame 60 consists simply of a base or tablet T, to the top of which an open-folding 5 gage-frame F is hinged, which has a central cross-bar which makes a right angle with the inner edge of the front member of the gageframe. This frame is used by placing a card on the tablet in proper position, folding down 7 the gage and fastening it with the catch 0. The previously-pasted pictures are then adjusted in position on the card by placing their inner bottom corners accurately in the angles formed by the cross-bar and the inner edge of the frame F, where they are lightly brushed down or simply stuck by their edges or corners, care being taken that the face of the print be not soiled or disturbed when a ferrotype-plate is applied to the print in the usual 30 way. On either side of the table is an endless belt 9, which is carried by the pulleys 3 3, placed one at each end of the table. This belt is called the picture-carrier, and it is driven by the belt 4, which connects pulley 3 with a 5 driving-pulley 62 on the driving-shaft 27. The action of the picture-carriers is governed by a tightener 48, which is placed under the control of the foot of the operative by the treadle 49, so that he may stop or start it at 9 pleasure. At the left-hand end of the table the paster sits and after pasting the backs of the prints lays them on the carriers 9 9, by which they are carried along opposite the mounters, sitting opposite the frames 60, by whom they are accurately stuck to the cards by the aid of the guide-frame F, as before described. After applying the ferrotype-plate to the face of the pack the mounter then lays the pack on another endless apron 6, which is I00 carried by pulleys or drums2and 45, by which pawl and ratchet mechanism which is conit is conveyed to the press-rolls 12 12. This 5 nected with the scape-wheel and box-carriage apron is called a conveyer and is provided by the motion of which the scape-wheel rowith cross-cleats 7 7 7, which act to push the tates a step as each pack passes from under pack onto the press-table l1 and into the grip 5 the press-rollers. Fig. 9. shows a transverse of the press-rolls. The conveyer runs c0n-,

stantly and is driven by pulley 63 on drivingshaft 27, through belt 5, which connects pulley 63 with pulley 2. Belt5 may also be regulated by a tightener 46, the tension of which is regulated by a spring 47 or by any other appropriate means. The press-rollers 12 12 are adjusted to give only a moderate pressure as the pack passes between them, so as simply to stick the several parts of the pack together. The rollers 1313 are adjusted to an intense pressure, which is designed to firmly close all parts firmly together. As the pack emerges from between the first pair of rollers it is forced under a tripping-roller 16, which lies across its path, and in doing solifts it slightly. Being hung in the arms of a rock-shaft 17, this slight rise efiects slight rotation of the rock-shaft, which causes a slight swing of the arm 18, which it carries on its outer end, as shown in Fig. 1. A rod 19 connects this tripper-arm 18 with an arm 20, carried on the end of the verge-shaft 51, (better seen in Figs. 4, 5, and 6,) which is provided with two pallets 54 and 55, which project from an arm 21, also carried by the verge. This verge is supported in bearings on two upright standards or posts 32 32, and the pallets engage pins 0, (Z, 6, and f of a scape-wheel 22, which is carried on the end of a double crank-shaft 23, which runs in bearings 43 43, also attached to said posts. On the opposite end of this crankshaft is a pulley 24, with which some driver (not shown) connects by a loose belt 57 whereby said shaft may be gently propelled, the purpose of this loose driving connection being to carry the crank-shaft over dead-centers, and also to act as a brake on the crankshaft to ease down the press-box when loaded. The cranks in this shaft are seen at a and 5, Figs. 7, 8, and 9, and are located midway between the posts 32 32. Each of these cranks or eccentrics carries a pawl 35 or 36, Figs. 7 and 8, pivoted thereon, having the weights 37 and 38, respectively, at their lower ends, which are so designed that gravity will normally actto throw the noses of the pawls toward the ratchets 33 33, which are attached to the back side of a carriage 31, on which the press-box is carried and which slides in the ways 64 of posts 32. Beneath the crankshaft 23 is a fulcrum-bar 39, which spans the interval between the posts, with which the lugs 41 and 42 at the lower ends of the pawls engage as the cranks carry the pawls around.

Fig. 7 illustrates the action of the cranks, pawls, and. lugs in connection with the ratchets and the fulcrum-bar. The cranks are set opposite each other, as seen in Fig. 9, so that when one pawl is ascending it will not engage its cooperating ratchet, but will be thrown into engagement therewith the instant its lug runs off the fulcrum-bar, so that its weight comes into action. The design is such that the nose of the pawl will throw into engagement a little in advance of its highest l l l l upward movement, and as the throw of the cranks slightly exceeds the length of a ratchettooth after the pawl has thrown in further rotation of the crank causes the nose of the pawl to engage the tooth above it and to lift it just enough to take the weight of the carriage and its load oif the nose of the other pawl, and this occurs just when the lug at its other crank is approaching the lower part of its throw and while the other lug is in engagement with the bar, so that further rotation of the shaft will draw the nose of the other pawl down and swing it away from the ratchet, the bar 39 serving to hold, it away from the ratchet until it has been carrie high enough to draw its lug off the bar, when the weight will act to throw it into position to engage the other ratchet. Thus the weight of the carriage and its load is suspended at all times upon the nose of one or the other of the pawls, and at each half-revolution of the shaft the carriage is given a slight upward hitch, which is barely enough to take the weight off the other pawl at the moment of its withdrawal from engagement with its corresponding ratchet.

A strongly-made box 311 is provided to receive the packs 0 as they are delivered from the roller-press which is carried on the boxcarriage 31. resting against the bracket 70, Fig. 1. The delivery of the packs after they have passed the tripper-roller 16 is effected by the press-rollers 13, which seize the packs as they are successively fed to them one after another and push them along until they reach the roller 24 at the end of the table 11. This roller is rotated by a belt from a pulley or belt-groove in one of the roller-arbors and operates to positively carry the pack along until it drops over the roller into the box. All this is clearly shown at C in Fig. 1, where the box is sho wn in position partially filled. When the box is full, it is removed from the carriage and another substituted. After removal the contents of the boxes are firmly pressed together therein and blocked, so that they can set and partially dry out in that condition.

The construction and operation of the escapement mechanism presents some novelties. The verge 21 is limited in its throw by the stationary pins 52 and 53. The dormant position of the scape-wheel and pallets is as seen in Fig. 4, with a pin, as (Z, resting on v the pallet 54. A swing of arm 21 over against stop-pin 52 releases pin d, and the scape-wheel rotates under the influence of belt 57 or the weight of the box-carriage until the following pin strikes the upper face of pallet 55; but this face being beveled or inclined the force or momentum of the scape-wheel will force it back until the back edge of arm 21 strikes stop-pin 53, at which moment pin 6 will slide off the pallet 55 and drop onto pallet 54,where it will rest until the tripper mechanism is again started by the passage of another pack under the tripper-roller 16, when this opera tion will be repeated. It will be noticed that the recoil movement of pallet 55 will reset the tripper-roller 16 for the next pack. wheel may be perforated for as many pins as may be found expedient, and the pins should be removable. This is desirable to accommodate the action of the press-box to the varying thicknesses of the packs. The object sought is to keep the top of the pile of packs in the press-box at just the proper elevation with reference to the delivery end of table 11 that as the packs fall over the roller 24 they will drop into true position in the box. There should be as many pins on each side of the scape-wheel as it requires packs to fill the box to the depth of one tooth of the ratchet.

It will be seen that the scape-wheel pins are not disposed around the entire periphery of the wheel or disk 22, but coincide with the position of the crank-wrists, which positions are indicated in Figs. 4. and 6 in dotted lines. The reason for this disposition is that the pawls can only move effectively in lowering the box-carriage when the crank-wrist is moving through that part of its orbit closest to and most nearly parallel with the line of ratchet-teeth, or, in other words, while it is traversing an arc of which the extremities are equidistant from a line drawn through the axis of the crank-shaft perpendicular to the line of movement of the ratchet-bar. It is plain that while the crank-wrist is traversing the dead-central parts of its orbit no appreciable movement will be imparted to the pawl. Hence the scape-pins are placed on the scapewheel opposite the non-effective parts of the orbitof movementof the crank-wrists. Therefore when the last scape-pin of the series has passed the pallet 54 the scape-wheel rotates without opposition around about a quarter of a revolution, more or less, carrying the upper pawl with it, and thus lowering the box until the leading scape-pin of the next series strikes pallet 55. Thus one complete revolution of the scape-wheel will lower the press-box two notches of the ratchet or a distance equivalent to the thickness of about eight packs as they are deposited in the box from the table 11 over the roller 24.
